Miniature rose plant Flameglo

ABSTRACT

The subject of the present disclosure is a new and distinct variety of miniature rose plant characterized by the very double flowers of yellow which become washed or tinted with red as they mature.

The present invention relates to a new and distinct variety of hardy,dwarf, bush type rose plant of the miniature class; the variety beingprimarily characterized--as to novelty--by the very double flowers ofyellow which become washed or tinted with red as they mature, which ingeneral color effect are similar to Circus, a Floribunda variety (U.S.Plant Pat. No. 1,382, expired).

The variety is further characterized by:

An abundance of bloom, with flowers usually borne singly on sturdy,slender stems.

Fragrance: slight.

A plant which is vigorous, of rounded somewhat upright shape with firmglossy, small foliage with pointed leaflets; the buds and flowers beingsimilar in form (but with more petals) to Over The Rainbow(miniature--U.S. Plant Pat. No. 3,472).

The plant, which has a normal height of 12-14 inches or more, can easilybe maintained at lesser height by occasional trimming.

A plant which grows and blooms satisfactorily both in greenhouse andoutdoors; is good for growing in pots; and provides excellent gardendecoration as well as cut flowers.

The present variety of miniature rose was originated by me at mynursery, located at Dallas, Tex. under conditions of careful control andobservation, as a cross between Starburst (U.S. Plant Pat. No. 2,974),as the seed parent and Over The Rainbow (miniature--U.S. Plant Pat. No.3,472), as the pollen parent.

Subsequent to origination of the variety I successfully reproduced it,at my nursery located as aforesaid, by cuttings; the reproductionshaving run true in all respects.

The color photograph illustrates the variety, including the foliage,buds and flowers.

Referring now specifically to the new and distinct variety of miniaturerose plant, the following is a detailed description thereof in outline;all major color plate identifications being by reference to the BritishColour Council Horticultural Colour Chart, except where common terms ofcolor definition are employed.

Type: Hardy; dwarf; bushy; upright; seedling; greenhouse; outdoors; cutflowers; garden decoration; potted plant.

Class: Miniature.

Variety name.--Flameglo.

Flowers borne: Usually singly on slender wirey stems.

Quantity of bloom: Abundant both outside and in greenhouse.

Bud:

Peduncle.--Medium length; slender but sturdy; erect; medium green,sometimes tinted bronze (outdoors); Hairs -- few or none. Before calyxbreaks; size -- small.

Form.--Ovid with some foliaceous appendages and few or no tiny hairs onsurface of bud; with foliaceous parts extending beyond the tip of thebud equal to one-half or less of its length.

Color.--Medium green, occasionally tinted with bronze (outdoors). Ascalyx breaks, color -- yellow. Opening: opens well in all weather.

Bloom:

Size when fully open.--Small -- (11/4").

Petalage.--Double -- arranged regularly, plus several small petaloids.

Form.--Imbricated, with petals reflexing loosely outward and later atmaturity, rolled loosely outward and downward. Open flowers usually showno stamens.

Petals: Fairly thick; satiny on inside and on outside surface.

Shape.--Outside petals, broad lanceolate (almost round) with rounded oracute tip; intermediate -- broad lanceolate with acute tip; inside --lanceolate with acute tip.

Color: Newly opened flower from a plant grown (Spring 1982), Dallas,Tex.

Outside petal.--Outside surface -- near Primrose Yellow 601/1 orlighter, sometimes green tint. Inside surface -- near Primrose Yellow601/1 or lighter.

Intermediate petal.--Outside surface -- similar to outside petal, butlittle or no greenish tint. Inside surface -- similar to outside petal.

Inner petal.--Outside surface -- similar to intermediate petal; insidesurface -- similar to intermediate petal. General color effect; newlyopened flower -- yellow at first (near Primrose Yellow 601/1 or lighter)gradually developing a reddish overlay on petal tips. Said red overlaydeveloping gradually, the intensity or depth of red being related to theamount of sunlight striking the flower. Only that portion of petal (topsurface) exposed to sunlight becomes red. The shades of red overlay canbe very light to a red color near Scarlet 19/1 (or similar -- said redoverlay often appears orange red due to the undertone of yellow. Threedays open -- color similar to newly opened flowers but yellow areabecoming more tinted or overlaid with red on tips of upper surface.Behavior -- opens well in all weather. Color lasts well even in hotweather. Red coloring more pronounced in full sunlight (outdoors) --more yellow and pink in greenhouse. Spent petals drop off. Flowerlongevity (April 1981) -- Plant in pot 6-8 days or longer. Cut flowersat living room temperature 4-5 days or longer.

Reproductive organs:

Stamens.--Usually none.

Filaments.--Usually none.

Anthers.--None.

Pollen.--None.

Pistils.--Malformed.

Ovaries.--All enclosed in calyx.

Hips.--None.

Sepals.--Permanent; spear shaped; recurved against peduncle.

Seed.--None.

Foliage:

Leaves.--Compound of five (sometimes three or seven) leaflets; fairlysmall; leathery; glossy.

Leaflets.--Shape: broad, nearly oval; apex acute; base rounded. Marginserrate. Color: Dark green; new growth -- normal (medium-green). Rachis:Medium strength; upper side may have a few tiny short prickles or hairs,grooved. Underside -- several small hooked thorns with few or no tinyprickles. Stipules: Medium long; narrow to medium width medium length;narrow points which turn out usually at about 45 degrees or more.

Growth:

Habit.--Dwarf; bushy; upright; much branched.

Growth.--Free vigorous; internodes short.

Canes.--Medium; slender; sturdy.

Main stems.--Color: Medium green.

thorns.--Average; slender; nearly straight, inclined slightly downward;color -- brown (tan). Prickles -- none. Hairs -- none.

Branches.--Color: Medium green. Thorns: Moderate number; medium length;slender; nearly straight, inclined downward. Medium oval base. Prickles:None. Hairs -- None.

The miniature rose plant and its flowers as herein described may vary inslight detail due to climatic, soil and cultural conditions under whichthe variety may be grown; the present description being of the varietyas grown at Dallas, Tex.

The following is claimed:
 1. A new and distinct variety of miniaturerose plant of hardy; dwarf; bushy; upright; much branched habit,substantially as illustrated and described, characterized by buds andflowers of medium yellow, with red or pinkish tint or overlay on petaltips as flowers mature, the bud and flower resembling the variety Circus(U.S. Plant Pat. No. 1,382, expired) in color and resembling the varietyOver The Rainbow in form and size; and further characterized by a plantof vigorous and compact growth habit, easy to propagate from cuttings,with an abundance of small to medium size glossy foliage and anabundance of flowers borne usually singly on sturdy wirey stems.
